A code of practice for media organisations embracing the phenomenon of 'citizen journalism' has been launched by the National Union of Journalists.

The Witness Contributors' Code of Practice outlines guidelines on issues such as accuracy and checking sources, along with payment to contributors.

It also covers copyright and other legal and moral rights and says that organisations should not do anything to encourage people to put themselves in danger in order to gain material.
